I've been a viewer during most of their relationship. While they had a connection (I did liked DeQuinn), it wasn't lost on me that Quinn was supporting him financially. According to Quinn, Deacon didn't need a job just "be there". Now we know that Quinn didn't really feel that way or else she wouldn't had asked for an annulment. It's easy to love a person flaws and all, when your getting sex and everything you want and need paid for. I'm not mad at Deacon for being a mooch. It's probably what Quinn deserved tbh.
The more I think about it, the more pissed I am at Deacon. He had the upper hand. Blackmail is smarter than straight up pulling a gun at the person. Ask Ivy.
